问题
I encountered a bizarre issue while using Android Studio (v2.3.3, built on 2017-06-06). One of my Java files was replaced with unrelated XML that seemed to be generated by Android Studio. I don't think I did anything to trigger it. A second Java file suffered the same fate soon afterwards, once again, with no discernible cause.
Thankfully I had just ZIPed up a copy of the source code so I deleted the files and replaced them. I don't have an exact copy of the weird code, but this code I found at git.moeryn.com is pretty close to what I saw:

I found somebody on StackOverflow who encountered a similar problem last week: My Activity Class turn into an xml file, however, there was no resolution or explanation of what happened. I found another instance of someone encountering the same problem here: Android Studio wrong load a source file
Now it has happened to me a third time - this time it affected an XML file in res/anim. This is really puzzling (and worrisome since I am now paranoid it'll happen again). Oddly enough, the file contents are cut off midway through a tag:
<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
<component name="AnalysisUIOptions">
<option name="SCOPE_TYPE" value="3" />
</component>
<component name="AndroidLayouts">

</component>
<component name="AndroidLogFilters">
<option name="TOOL_WINDOW_LOG_LEVEL" value="verbose" />
<option name="TOOL_WINDOW_CONFIGURED_FILTER" value="Show only selected application" />
</component>
<component name="BookmarkManager">
<bookmar
Has anyone else encountered this problem? Any idea what might be causing it?
It happened a few more times when I opened XML files. transition__dialog__slide_out_to_right.xml was replaced with the beginning of my FlagView.java class that I was working on earlier (note that the Java file wasn't open at the time, it had been 2+ hours since I'd been editing it, and this code wasn't in my clipboard):
package co.company.app.views;
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.PorterDuff;
import android.graphics.drawable.Drawable;
import android.support.v7.app.AppCompatDelegate;
import android.util.AttributeSet;
import android.
transition__dialog__slide_in_from_right.xml got replaced with this partial XML:
<application>
<component name="UsageTrigger">
<counts>
<entry feature="CreateFile.CreateFileAction" count="2" />
<entry feature="execute.AndroidRunConfigurationType.Debug" count="14" />
<entry feature="execute.AndroidRunConfigurationType.Run" count="2237" />
<entry feature="execute.GradleRunCon
The other transition anim files opened normally. However, another file in res/anim got replaced with most of my Canadian flag drawable XML file:
<!-- Canadian flag -->
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="48dp"
android:height="24dp"
android:viewportWidth="1000.0"

Very bizarre...
I closed Android Studio, and when I reopened it, it was using the default light theme instead of my dark theme. A list of errors appeared on the right side of the screen. I closed the application and reopened it. This time I got a popup saying Start Failed:

Something seems to have gone terribly wrong with Android Studio...
回答1:
I didn't uncover the root cause of the issue, but following Yashasvi's prompt and the fortunate timing of Android Studio v3's release (5 days before my question on 2017-10-25), I upgraded the software and everything has been working fine since.
Not the most satisfying conclusion to my question, but the my code isn't being screwed up and I'm happy.
